Since we 'continue' the loop if num_search_results is 0, there is no need for
the second check.

This patch adds a new configuration setting, selection-clipboard, which allows
us to choose between the PRIMARY selection, and the CLIPBOARD selection, for
determining which X clipboard to use for storing mouse-selected data. It has
only two valid values: "primary" and "clipboard", with "clipboard" being set as
the it's default value.

Otherwise, when opening a document at page 1, and no jumps are added,
bisect does not understand it has to initialize the bisect range, and
does not move from page 1.

- Allow the user to always start with the very last (or first) jump on the
jumplist when pressing ^o (or ^i), while the jumplist iterator is
pointing to the last (or first) jump, and the document is not currently
at the position of this pointed-to jump. This is instead of jumping
directly to the previous/next jump, and skipping the last/first one.
- Don't jump to the current jump pointed to by the jumplist iterator, if
there is no more next jumps, and the jump direction is FORWARD.
- Don't jump to the current jump pointed to by the jumplist iterator, if
there is no more previous jumps, and the jump direction is BACKWARD.

- Don't delete the elements on the right of the current one, when
appending a new jump to the jumplist, because this makes no sense at
all; the point of the jumplist in the first place is to remember
previously jumped-to positions in the document, so there is no need
to delete anythings except to trim the oldest entries from the
beginning to maintain the maximum size. This also makes us compatible
with the Vim way of doing things.
- Make the jumplist mechanism functional on the same page; if we
followed a link to a target on the same page, remember the
adjustments before and after following the link. The same holds for
navigating search results on the same page.
- Implement position_set and use it instead of position_set_delayed
when following links in order to give zathura_jumplist_save a chance
to record the exact adjustments of the link target. Otherwise, it
will always record the adjustments after going to the target page,
but before going to the exact position within it.
- Don't consider movements with ^i and ^o as jumps :)
- Don't use page_set followed by setting the adjustments in
sc_jumplist, because this is redundant and causes clutter when using
^i and ^o, as the adjustments is set twice this way (once in page_set
and again in position_set_delayed). It's enough to only update the
page number on the statusbar and then set the adjustments.
- Hide implementation details (zathura_jumplist_save and
zathura_jumplist_append), and make things more consistent by
exporting and using only zathura_jumplist_add for adding new entries.
The end result: A more slick jumping experience :-)

This patch activates the last aborted search when pressing the search shortcuts
('n' or 'N').
To avoid confusion, and to make things more predictable, I've chosen to always
reactivate an aborted search starting from the beginning (or end, in case of
'N' or '?') of the current page, as opposed to Vim which continues from the
next search term each time the search is reactivated.
Searching using '/' or '?' doesn't center the view at the current search term
like when using 'n' or 'N', so we fix this here.
Also, I managed to work around the issue of the thin rectangular margins that
show around the previously-highlighted search terms after the search is aborted
(either explicitly or as a result of following links), by redrawing the page
widget (only if it's visible) instead of redrawing the rectangles covering the
highlighted search terms.

This uses the jumplist to implement a bisect functionality between the
last two jump points. ^j and ^k are bound to bisect forward and backward
respectively.

Add a new adjust mode that is set when focusing the inputbar and
disables adjusting the vertical scrollbar. As a result, focusing the
inputbar doesn't scroll the document, leading to better results when
changing pages from the inputbar (e.g. using bookmarks).

Instead of guesstimating the values of the scrollbars adjustments after
a change in zoom level, connect callbacks to the "changed" GtkAdjustment
event (which is emitted when the bounds or page_size of the adjustment
change, e.g. when the zoom level changes), and compute the new values
from there.
The previous adjustment values are tracked in zathura->ui.hadjustment
and zathura->ui.vadjustment (and updated by signal handlers as well), so
that the view's position can be maintained while zooming.
cb_view_hadjustment_changed() centers the page horizontally if a
"best-fit" or "width" zoom is being performed, or if "zoom-center" is
true; otherwise, it keeps the view horizontally centered around the same
area of the page.
cb_view_vadjustment_changed() always keeps the view vertically centered
around the same area of the page.
Many thanks to Marwan Tanager for thoroughly reviewing the various
stages of this patch, and actually coming up with a working solution.

This wasn't correct. Padding is already accounted for:
scale = (width - (pages_per_row - 1) * padding) /
(pages_per_row * cell_width)
If you add padding on the denominator, you end up with black margins on
the sides of the window, which isn't what padding is for (i.e. insert a
gap between rendered pages), and defeats the purpose of a "best-fit".

If '--page [number]' (or '-P [number]') is given on the command-line,
the document is opened at the specified page number. Negative numbers
are allowed, and denote a page number starting from the end of the
document.

The width of the vertical scrollbar (if there is one) needs to be
substracted from the width of the GtkScrolledWindow in order to obtain
the correct dimensions of the view area.
See issue 27 <http://bugs.pwmt.org/issue27>.
It also deals better with documents where pages don't all have the same
size.

The scroll-wrap option used to only change the behavior of 'J' and 'K'
(i.e. moving one page forward/backward).
Now, if scroll-wrap is true and the top of the first page is shown,
pressing 'k' will show the bottom of the last page; conversely, when at
the bottom of the last page, pressing 'j' will show the top of the first
page.
